The Universe Around Us

Abstract

IN the decade that has elapsed since the third edition of this well-known book, many advances in astronomy have been made. Sir James Jeans has incorporated reference to many of these in the new edition, and has taken the opportunity to make a thorough revision and to rewrite a large part of the book. Thus, for example, reference is made to the recent discovery of companions of small mass belonging to the systems of 61 Cygni and 70 Ophiuchi; some account is given of Eddington's investigations on the expansion of the universe and the rate of recession of the extra-galactic nebulæ; and the bearing of the new knowledge of the source of stellar energy, derived from the study of thermonuclear reactions, on the evolution of the stars is described.
